We are using a CM-T3730 with Linux kernel 3.0.50. We have recently noticed dpll1_ck "could not enable: -22" errors with very slow application times. (see arch/arm/mach-omap2/clock.c)
We can "fix" the problem by unplugging the device for 20+ seconds, but we would like to correctly initialize the device.
I assume that we are either mis-ordering the initialization sequence or missing a part of it. If anyone can give hints to the root cause of the errors, I'd love to hear from you.
